Osteoarthritis is a form of arthritis that occurs when the cartilage that protects the bone ends wears over time, according to Mayo Clinic. It is the most common type of arthritis, and it typically attacks the hand, knee, spine and hip joints. Although rare, it also attacks other body joints.
The symptoms of osteoarthritis include joint pain, joint tenderness, especially when pressure is applied to it, stiff joints and joint inflexibility, claims Mayo Clinic. These symptoms have a slower growth rate and deteriorate with time. Although osteoarthritis has no cure, its growth can be slowed down by maintaining a healthy body weight and staying active.
